FCB, New York, is considered the incumbent; the agency's San Francisco office held the wireless account since 1995.

The four agencies were informed today of the decision. The three finalists now will advance to a session with top executives from AT&T Wireless including Chairman-CEO John Zeglis. That session is tentatively slated for June 29 at an off-site location as yet to be determined.

At the meeting, the agencies will present an executive summary, after which a decision is expected fairly quickly. AT&T Wireless has set July 9 for its spin-off from AT&T Corp. -- Tobi Elkin
